I've been trying to set up a timer and DMA to run a synchronous parallel bus onto a GPIO. The timer works great but the DMA keeps failing with a transaction error interrupt and disables the stream. This is on an STM32F413 chip and using TIM2_CH1 as a...
Hi there, We are having some issues with our STM32H7 when the MCU is heated above approximately 55C. This leads to a fault of some form within the STM32 which prevents it from reading an external flash which the code is being run from. This memory is...
When using HAL_SPI_Transmit_DMA with STM32743, must the transmission data buffer and reception data buffer be placed in D1 RAM?Also, is there a way to dynamically allocate D1 RAM? Rather than declaring an array placed in section("D1"), I would like t...
Hello, New here. I am working with a piece of consumer electronics equipment that uses a STM32F101C8 processor. the customer was doing an update to this unit and in the middle of the update, pulled the USB plug out of his computer bricking the unit. ...
I soldered a new STM32 on the board, it can enter bootloader, but it's under Readout protection(I guess I bought renovated chip), I don't know how to unlock Readout by STM32CubeProgramer, finally, I use STVP and ST-LINK V1 to connect through SWD, and...
I am trying to use stm32flash to program my board over UART. I understand that the board needs to be in boot mode in order for this to be accomplished, so using the STM32CubeProgrammer I have tried setting the resisters appropriately. BOOT_lOCK: set ...
I want to use the ULPI interface & both the CAN interface for my project But I see For USB: Pin No: 194 pin name: PB5 Module function : USB_OTG_HS_ULPI_D7, ONLY ONE PIN no other pins are there For CAN Pin No: 194,195 pin name: PB...
Hello, I am developing an application using STM32N657I have datasheet DS14791 Rev 4. There are pins for VDDIO2 to VDDIO5 and the datasheet implies that I can run the GPIO on an independent voltage supply. Chapter 5.3.17 even specifies low levels and ...
I am trying to get a 7" LCD to interface with a STM32F407VET6 microcontroller. I am using a display from winstar which the product number is WF70A2TIFGDBT0. The screen is 800x480 pixels and uses 8080 interface. The display uses a SSD1963 driver and I...
I am unsure if I correctly understand the power consumption of the N6 Family. I want to supply the MCU with 1,8V and use the internal SMPS to supply Core with 0,81V.When it comes to designing the 1,8V voltage source, how much current do I have to exp...
